## What is Ethanol Top?

Ethanol Top-Off tells you exactly how much ethanol (or gasoline) to add to your tank to hit the blend percentage you're tuning for.

If you run E85, flex-fuel, or mix your own blend for a track car, you already know pump ethanol content varies and doing the math at the gas station gets old fast. Enter your tank size, your best estimate of what's already in there, and your target percentage — Ethanol Top-Off gives you the exact volume to add.

- Simple slider-and-stepper inputs, no fiddly keyboards
- Instant results as you adjust any value
- Works both directions — blend up or dilute down
- No account, no ads, no internet connection needed
- Nothing you type ever leaves your phone
